Title: Improvements in and relating to Valve Mechanism.
IPC: F01D1/02
Filed: 1916-03-15
Abstract: 104,732. British Thomson-Houston Co., and Halliwell, R. F. March 15, 1916. Regulating.-Relates to valve mechanism particularly for mixed-pressure turbines comprising a single valve for the lowpressure supply adapted to act as a governing- valve and also as a handoperated stop valve, an emergency valve, and an automatic shut-off valve. The valve 1, Fig. 1, admitting low - pressure steam from an accumulator &c. to the turbine conduit 3, is connected to a rocking lever 5 actuated at one end by a piston 13 subjected below by means of an aperture 14 to the steam pressure at the inlet 2, and at the other end by a hand-operated screwed rod 8 so that the valve may be utilized as a manually-operated stop valve. When a handlever 11 is operated to release a trigger, a spring 10 forces down the rod 8, and the valve acts as a manually-released emergency valve. A cam shaft 23, carrying cams for operating the high-pressure valves in the usual manner, is adapted to actuate through the fluid-relay device shown, or by mechanical connexions, a stem 17 for engaging the valve cross-head 4. When closing down, the high-pressure valves close before the low-pressure controlling-gear closes the low-pressure valve. When running the turbine in parallel with other sets, the governor and the main controlling-piston operating the cam shaft are connected as shown, for example, in Specification 20326/11. In a modification, Fig. 2, the stem 17 is connected to one end of the lever 5, and the pressure-responsive device 13 operates the valve 1 through the fluidrelay device 16. The arrangement is such that, if the steam pressure at the inlet is less than atmospheric pressure, the bell-crank lever 22 is unable to move the pilot valve 18 sufficiently to open the valve 1.

Abstract: 418,132. Thermionic valves. TELEFUNKEN GES. FUR DRAHTLOSE TELEGRAPHIE, 12, Hallesches Ufer, Berlin. Feb. 13, 1933, No. 4412. Convention date, Feb. 11, 1932. [Class 39 (i).] A valve has an anode A, a control grid G, and a cathode K of regulatable electron density and velocity consisting of an electron-emitting member C and at least two grids G<1>, G<2> in the electron stream between the emitting member and the control grid, constant potentials, not varying with signals, being applied to the grids G<1>, G<2> so that the potential on the inner grid G<1> mainly determines the electron density, and the potential on the outer grid G<2> mainly determines the electron velocity. The emitting member C or the grid G<2> may be earthed ; with the member C earthed, the potentials in the other electrodes may be + 20 volts on G <1>, + 50 volts on G<2>, - 50 volts on G, and + 100 volts on A. The electrodes are mounted concentrically, and the arrangement is such that the amplification factor is greater than 10, so that the anode field acting through the control grid on the "regulating cathode" is small. A screen grid may be mounted between the control grid and anode, the arrangement being such that with the "regulating cathode," the control grid and the screen grid regarded as a triode, the amplification factor is greater than 10. A grid may be arranged between the grids G', G<2> and maintained at an intermediate potential so as to enable completely independent regulation of electron density and velocity to be obtained. The gas filling, unspecified, has a pressure of 10<-2> to 10<-4> mm. such that no appreciable ionization occurs. Condensers having some loss are mounted in the valve between the " regulating cathode " and the emitting element. A magnetic field at right angles to the discharge may be produced by a magnet, the "regulating cathode" being of non-ferro-magnetic material and the anode of similar material or slit.

Abstract: 100,211. Fiat-San Giorgio Soc. Anon. Jan. 14, 1915, [Convention date]. Launching torpedoes. - Consists in providing a torpedo tube with an adjustable stop-device to enable the same tube to be used for torpedoes of different lengths. In the form shown in Figs. 2 and 3. two shafts P, C are mounted in a casing Q alongside the torpedo tube B. The shaft C can slide but cannot rotate, and carries a block D which supports spur-wheels E, H and the screw stop F. The other shaft can both slide and rotate, and carries a rack block G<1> over a screw-threaded part P' of the shaft, the rack being geared to the wheel E through the intermediate wheel H. The two shafts are geared together by a wheel I on a square part of the shaft P, idle wheel L, and wheel M on a screw-threaded part on the shaft C, these threads being of the same pitch as the threads P<1>, and the three wheels being of the same size. Thus, by rotating the shaft P, the rack block G<1> and the shaft C, together with the block D, wheels E, H, and stop F, are displaced longitudinally to adjust the position of the stop according to the length of the torpedo; and a longitudinal displacement of the shaft P causes the wheels E, H to be rotated by the rack G', and this rotation is arranged to screw the stop I into or out of action, as the case may be.

Title: Improvements in or relating to synchronising circuits for television receivers
IPC: H04N5/12
Filed: 1955-02-18
Abstract: 798,773. Automatic synchronizing systems. TELEFUNKEN GES. Feb. 18, 1955 [Feb. 20, 1954], No. 4859/55. Class 38 (4). [Also in Group XL (c)] In a flywheel synchronising system for television receivers, voltage pulses derived by differentiating the rear edges of received linesynchronizing pulses are used for phase comparison with the short flanks of the sawtooth deflection waves. Differentiated pulses may be obtained from the anode circuit of a valve having a C-R or L-R differentiating circuit, the time constant of which is such that the leading differentiated pulse has no effect on the trailing differentiated pulse, or the leading pulse may be removed by a shunt diode or a triode threshold circuit. As shown, Fig. 19, differentiated line synchronizing pulses are derived from a transformer 91 and applied via capacitors 105, 106 to the grid of a phase comparison triode 107 which is gated and whose mutual conductance is periodically increased by flyback pulses applied to its anode from a blocking oscillator timebase generator 119 and to the junction of the capacitors 105, 106, a sawtooth voltage being applied from the line deflection generator 16. A control voltage is thereby derived from the cathode circuit of the valve 107 dependent on the phase relation between the positive-going differentiated pulses applied to the valve 107 and the sawtooth flyback voltage, which after smoothing is applied to the grid of the blocking oscillator 119 to phase lock it. A compensating voltage applied to the cathode circuit of valve 107 from the cathode circuit of valve. 102 allows for the greater duration of conduction during picture flyback. In fig, 4, capacitor 93 and resistor 94 differentiate the input negative-going line synchronizing pulses to a biased. triode 95 so that only pulses due to the rear edges are derived across a transformer 150 in the anode circuit of the valve. Flyback pulses 151 from the deflection generator 16 are also differentiated by the capacitor-resistor circuit 152, 153 to derive the waveform 154 applied to the centre-tap of the transformer secondary. A differential voltage from the two series of superimposed pulses (one shown at 161) is therefore derived from the output of the rectifiers 155, 156 and, after smoothing, applied to phase-lock the blocking oscillator or multi-vibrator time-base generator 14. It is shown that the use of the rear edge of the synchronizing pulse avoids the positional change, due to circuit time constants, of the derived line synchronizing pulses when lines, for some length of time, change from ending in white to ending in black. Specification 753,871 is referred to.
